Catalytic Converter Cleaner new technology effective cleaning solution

Our review finds the Catalytic Converter Cleaner new technology kit best suited for owners who suspect their catalyst is clogged but not mechanically damaged. In this review the single biggest reason to try this kit is its two-part approach: a tank additive and a foam spray that together target internal deposits without removing the converter. It is aimed at motorists who want an inexpensive alternative to replacing a catalytic converter and who are willing to inspect the unit for cracks before use.

Key Features

• Two-part system: Includes a fuel tank additive and a foam spray so deposits are treated both from fuel flow and by direct application through the O2 sensor port.
• No disassembly required: The foam cleaner is applied through the sensor port and the tank product is poured in, avoiding removal of the catalytic converter.
• Designed to restore performance: The formula targets deposit buildup to help restore engine response and exhaust flow.
• Compatibility: Formulated for petrol, diesel and hybrid vehicles so one kit covers a broad range of engines.
• Cost effective alternative: Advertised as an inexpensive option intended to clean the catalyst instead of replacing it, which can save significant repair cost if the substrate is intact.

Who It's For

This kit is a practical choice for DIY mechanics and vehicle owners who see signs of catalyst fouling, such as reduced performance or pending P0420 / P0430 codes, and who confirm the catalytic converter has no visible cracks. It suits drivers looking for a lower-cost intervention before considering a replacement.

It is not for vehicles with a physically broken or cracked catalyst, or for users who need guaranteed results in every case; some users report mixed effectiveness and possible persistent engine light conditions, so professional diagnosis is still recommended for unclear faults.

Pros & Cons

Pros

• Targets deposits both internally and externally with a combined tank and foam approach.
• Easy to use without removing the catalytic converter or complex tools.
• Works across petrol, diesel and hybrid platforms for versatile application.

Cons

• Effectiveness is mixed in user reports and may not clear every code or fault if the catalyst is damaged.
• Some customers reported the engine light returning after short driving distances, indicating results can vary by vehicle condition.

Our Verdict

The Catalytic Converter Cleaner kit is a sensible, low-cost first step for owners who find deposits have reduced exhaust or engine performance and who confirm the catalyst is structurally sound. Its two-part method and ease of use make it good value for vehicles with fouling rather than physical damage, but users should accept variable results and consider professional inspection if codes persist.

Frequently Asked Questions

Will this fix P0420 or P0430 codes?
If the codes are caused by deposit buildup and the catalyst substrate is intact, the kit can clear or reduce those codes, but it will not repair a physically broken converter.

Do I need to remove the catalytic converter?
No, the product is applied via the fuel tank and a foam spray through the O2 sensor port so disassembly is not required.

Is it safe for diesel and hybrid engines?
Yes, the formula is stated for use in petrol, diesel and hybrid vehicles, but inspect the catalyst for cracks before use.
